CORTES MORA, Jimmy A; COTES TORRES, Alejandro  e  COTES TORRES, José M. Structural features of dual-purpose cattle production system in the Colombian humid tropic. Rev Colom Cienc Pecua [online]. 2012, vol.25, n.2, pp.229-239. ISSN 0120-0690.

Objective: to identify the main biophysical, technological, social, and economic features of dual- purpose cattle system (DPCS) in the low Colombian tropic. Methods: detail surveys were conducted through technical visits to 14 farms at the Piedemonte Llanero region in Meta and Casanare provinces. The information obtained was processed by multi-variance analysis. Results: two main factors accounted for 93.34% of the total variance found in the system: 1) economic-business (EB) capability, and 2) technological capability (TC). A biplot graphic allowed identifying four types of interactions between these factors, as follows: 1) high EB and TC, 2) high EB but low TC, 3) low EB but high TC, and 4) low EB and TC. Conclusions: feeding is the most important constraint for the DPCS having low EB and high TC, while pasture management, genetic, and reproductive variables were the most important factors for the DPCS with high EB and TC.
